2 .Claims.

invention relates to ;-gOggles :for eye protction.

The invention has particular relation to the provision of a g ggle forindustrial eye protection purposes by personnel working under conditionsinvolving exposure to gas or possible splashing of corrosive li uids,and the principal object of the invention is to provide a go gle forsuch purposes which is adequately gas tight to assure proper protectionto the eyes of the wearer lander such working conditions, while at thesame time including a lens sealed into the frame for protective actionuse but quickly and easily replaceable in the event of abrasion or otherdamage thereto.

Other objects and advantages of the invention will the apparent from thefollowing description, the accompanying drawing and the appended claims.

In the drawing- Fig. 1 is a view in front elevation illustrating agoggle constructed in accordance with the invention, the view being'partly broken away substantially on the center of the goggle :lens toillustrate details of internal construction;

Fig. 2 is a fragmentary top plan view of the og le;

Rig. .3 is a section on the line 33 of Fig. 1; and

line 4-4 of Fig. l and ona larger scale.

In the drawing, which illustrates a preferred embodiment of theinvention, the goggle is shown as including a one-piece frame which isreadily molded from rubber or like material of suitable flexibility.This frame includes a front rim portion [0 and a portion II whichextends rearwardly from the rim to define the eye chamber of the goggle,and the frame portion ll terminates in a double flange portion 12 and I3for engaging the face of the wearer. As shown in Figs. 3 and 4, theouter flange I2 is formed to fit smoothly around the goggle against theforehead, temples and checks of the wearer but is relieved at the nosereceiving portion of the goggle, and the flange portion l3 extendsgenerally inwardly from the frame portion H for similarly seatingagainst the face of the wearer and includes a central web portion l5adapted to seat on the bridge of the nose of the wearer to complete thesealing action goggle frame and the wearers face.

The rim ID of the goggle is formed to define a single viewing aperturecomprising a pair of enlarged eye portions and. a connecting portion ofreduced vertical extent at the center of the Fig. 4 is a fragmentarysection taken on the in the junction between the goggle and above thewearers nose. A lens on complementary shape to the rim is receivedtherein, and this lens may be formed of a suitable transparent plasticmaterial, satisfactory results having been obtained wi-th celluloseacetate. In order to seal the lens in the frame while still providingfor ready removal and replacement thereof "in the event of scratching orother damage to the lens, the rim to is formed to include a pair offlange portions 2.l and 22 which cooperate to define a channel forreceiving the periphery of the lens .as best seen in Figs. and +1. Theseflange portions overlap a strip along the edge of the lens of sufficientwidth to assure adequate sealing against the passage of gas or l-i.q uidaround the edge of the lens into the eye chamber from without. ,Also,the flanges 2 and .22 are formed at :the center portion of thegoss cwith extensions of su-fiicient area to receive at pair of :bolts 25which extend through holes the lens and are provided with cooperatingnuts .26. With these bolts and nuts formed of stainless steel, the lensis firmly secured within the frame against possible accidental:dislodgment in use, while at the same time upon removal of the nuts andbolts, the-lens can be quickly and easily snapped out of the frame andreplaced with anew lens when adesired.

A head strap :30 is provided for securing the go gle position on thehead of the wearer. order :to attach this iheadptrap to the ogglewithout the possibility of creating an opening capable of admittingcorrosive fluid into the interior of the eye chamber, the goggle frameis formed at either end with a lug portion 3| having a slot therethroughfor receiving the head strap. Each end of the head strap is formed withan enlarged portion 32, and a metal or plastic grommet or plate 33slotted to receive the strap is positioned thereon between theenlargement 32 and the front of each lug 3|. With the strap thusconnected with the frame at its ends and entirely exteriorly of the eyechamber, the frame readily adapts itself to the face of the wearer toprovide the desired closely sealed fit in place.

It will accordingly be seen that when this goggle is assembled asdescribed with the flexible lens and attaching bolts therefor in placeand is fitted on a wearer, the eye chamber of the goggle is entirelysealed against the possible passage of corrosive fluids capable ofinjuring the wearers eyes, theflanges I2 and 13 providing an effectiveseal at the junction between the goggle frame and the face, and theframe being entirely free of openings, including even ventilationopenings, which might otherwise permit gas to pass therethrough. At thesame time, the goggle provides the advantages of light weight andcomfort as well as adaptability to faces and heads of difierent sizesand shapes which cannot readily be obtained with a glass or like rigidlens construction. Furthermore, if the plastic lens is damaged or worn,it is quickly and easily replaced without affecting the wearability orsealed construction of the goggle.

While the form of apparatus herein described constitutes a preferredembodiment of the invention, it is to be understood that the inventionis not limited to this precise form of apparatus, and that changes maybe made therein without departing from the scope of the invention whichis defined in the appended claims.

What is claimed is:

1. A goggle of the single aperture and replaceable lens type forprotection against gas, corrosive liquids and the like comprising aonepiece frame including a, front rim portion and a portion extendingrearwardly from said rim to define an eye chamber, a peripheral flangeon said rearwardly extending portion adapted to fit closely against theface of the wearer to seal the junction therebetween, said rim defininga pair of eye apertures connected by a portion of reduced verticalextent above the nose of the wearer, a one-piece lens of flexiblematerial adapted to be received within said rim and of complementaryshape thereto, inner and outer spaced flanges on the inner periphery ofsaid rim forming a channel for receiving the periphery of said lens,locking means extending through said flanges and said lens for securingsaid lens in compressed relation between said flanges to seal againstthe passage of gas around the edge thereof into the interior of said eyechamber, said locking means being releasable to provide for readyremoval and replacement of said lens, said frame being entirely free ofopenings into said eye chamber except for said lens receiving portion toseal said eye chamber against the passage of gas from without, a headstrap for supporting said frame on the head of the wearer, and means forsecuring the ends of said head strap to said frame entirely exteriorlyof said eye chamber to maintain said eye chamber sealed against gas inposition on the head of the wearer.

2. A goggle of the single aperture and replaceable lens type forprotection against gas, corrosive liquids and the like comprising aone-piece frame including a front rim portion and a portion extendingrearwardly from said rim to define an eyechamber, a peripheral flange onsaid rearwardly extending portion adapted to fit closely against theface of the wearer to seal the junction therebetween, said rim defininga pair of eye apertures connected by a portion of reduced verticalextent above the nose of the wearer, a one-piece lens of flexiblematerial adapted to be received within said rim and of complementaryshape thereto, cooperating inner and outer spaced flange portions on theinner periphery of said rim forming a channel for receiving theperiphery of said lens in close fitting relation to seal against thepassage of gas around the edge of said lens into said eye chamber, aplurality of bolts extending through said flange portions and said lens,cooperating nuts on said bolts for compressing said lens into releasablysealed relation between said flange portions while providing for readyremoval and replacement of said lens, said frame being entirely free ofopenings into said eye chamber except for said lens receiving portion toseal said eye chamber against the passage of gas from without, aheadstrap for supporting said frame on the head of the wearer, said framehaving an apertured lug portion at each end thereof for receiving saidstrap therethrough, and means for securing said strap to said lugs toeffect attachment of said head strap to said frame entirely exteriorlyof said eye chamber to maintain said eye chamber sealed against gas inposition on the head of the wearer.
